Santa Monica housing facts (Census 2020–2024)
Planning your project
Most homes in Santa Monica are older. The Census counts 73.4% of housing units built before 1980, and the median year built is 1968. That makes the existing system, ducts and electrical panel the first things to check before you pick an AC or furnace.
What Santa Monica's homes mean for your HVAC system (AC or furnace)
Older ductwork may leak, be undersized, or have insulation or tape that needs testing. Ask the builder to check it before you choose a new system. Central AC or a heat pump can also need more electrical capacity than an older panel provides.
The Census reports 27.9% of occupied Santa Monica housing units as owner-occupied, so many projects are in rental homes. If you own a rental, plan the work with your tenants. Tell them the schedule early and agree on access times.
The median value of owner-occupied homes is $1,755,500. Use that figure only to think about how much to put into the home relative to its value. Ductless systems can be an option for homes without ducts.

Assess the home
Ask the builder to check the size of the home, insulation, existing ducts, the electrical panel, and venting. In older homes, look closely at duct condition, any old insulation, and clearances around furnaces.
Choose the system
Compare central AC, a heat pump, a furnace, or ductless units. Your home's layout, ducts, and electrical capacity will shape which options fit.
Get the mechanical permit
Your builder can check which permits apply to your project. Confirm with the city what is needed before work starts, and do not assume the process is the same for every home.
Installation
The installer removes the old unit where needed, sets the new equipment, and connects ducts, power and venting. Plan for the work to be scheduled around any tenants.
Inspection and sign-off
An inspection checks the work against the permit. Once it passes, the city gives sign-off. Keep the paperwork with your home records.
Questions about HVAC in Santa Monica
Does the age of Santa Monica housing change an HVAC project?
Often, yes. The Census counts 73.4% of Santa Monica housing units as built before 1980, and the median year built is 1968. Older homes can have ductwork that leaks, is undersized, or has old insulation or tape that needs testing. Ask the builder to check these before choosing a system.
What should a landlord consider with 27.9% owner-occupied housing in Santa Monica?
Owners who rent out a property should plan the work with the tenant in mind. Tell tenants about the schedule early, agree on access times, and plan for how long heating or cooling may be limited. The Census reports 27.9% of occupied Santa Monica housing units as owner-occupied, so many projects involve rental homes.
How should I think about budget against a $1,755,500 median home value?
Compare the likely cost of the system with the value of your home. The Census median value of owner-occupied homes in Santa Monica is $1,755,500. This figure is a general market measure, not a price for your home. Use it only to think about how much to spend relative to the property's value.
What should I ask a builder to check before installation?
Ask the builder to check the size of the home, insulation, ductwork, the electrical panel, and venting. For older homes, these checks matter most. A written scope helps you compare what each option includes.
How can I check a contractor's license status?
Check any contractor's license status with the CSLB (Contractors State License Board) before you agree to work. The CSLB site shows the status of a contractor's license.
